FRAMINGHAM, Mass., Feb. 27, 2014 /PRNewswire/ -- HeartWare International, Inc. (NASDAQ: HTWR), a leading innovator of less invasive, miniaturized circulatory support technologies that are revolutionizing the treatment of advanced heart failure, today announced revenue of $53.1 million for the fourth quarter ended December 31, 2013, a 62% increase compared to $32.7 million in revenue for the same period of 2012. For the fiscal year 2013, the company generated revenue of $207.9 million, an 87% increase compared to revenue of $110.9 million in fiscal year 2012.

"We experienced strong market adoption of the HeartWare® Ventricular Assist System during our first full year of U.S. commercialization, with nearly 1,000 units sold and a total of 96 U.S. customers at the close of the year," said Doug Godshall, President and Chief Executive Officer. "In addition, we continue to receive enthusiastic support from markets outside of the U.S., with the addition of 28 international customers in new and existing markets. We are proud to have finished the year with 230 customers worldwide, an increase of nearly 50% in 2013."

During the fourth quarter, 524 HeartWare Systems were sold globally, a 52% increase from 345 units in the fourth quarter of 2012. U.S. revenue during the fourth quarter of 2013 was $25.9 million, a 94% increase from $13.4 million in the fourth quarter of 2012. Revenue from international markets, generated through the sale of 282 units, was $27.1 million, an increase of approximately 41% from $19.3 million in the fourth quarter of 2012.

"Our strong commercial growth was complemented by advances made in the clinical development of the HeartWare System," added Mr. Godshall. "During 2013, we initiated enrollment in the U.S. for our supplemental cohort study for destination therapy, received approval to commence enrollment in our trial in Japan, and we obtained conditional approval from the FDA for our U.S. thoracotomy trial. We are eagerly anticipating the upcoming initiation of first-in-human testing of our next generation MVAD® pump and Pal™ peripherals, which is expected to precede the commencement of a 63-patient, CE Mark study at nine international hospital sites.

"The acquisition of CircuLite, developer of the SYNERGY® Circulatory Support System, in December 2013, provides an opportunity for us to expand our core business into the partial-support market segment, through the treatment of heart failure patients who are less sick," Mr. Godshall said. "Our team is working diligently to make refinements to this device in order to position the SYNERGY System for re-launch at select European sites and to enhance the SYNERGY® Endovascular System when it enters the clinic."

Currency fluctuations benefitted revenue growth by approximately two percentage points in the fourth quarter, as well as on a full-year basis, in 2013 compared to the same periods in 2012.

Total operating expenses for the fourth quarter of 2013 were $53.3 million, as compared to $35.4 million in the fourth quarter of 2012. Total operating expenses included CircuLite's results for the month of December.

Research and development expense was $30.3 million for the fourth quarter of 2013, as compared to $22.2 million in the same period of 2012. Development costs are primarily attributable to clinical trials and research and development related to advancing HeartWare's existing products and pipeline technologies.

Selling, general and administrative expenses were $23.0 million in the fourth quarter of 2013, compared to $13.3 million in the fourth quarter of 2012. The increase in selling, general and administrative expenses reflects expansion of sales and marketing activities, particularly in the U.S., and an overall increase in corporate infrastructure to support the company's significant growth.

Net loss for the fourth quarter of 2013 was $22.0 million, or a $1.33 loss per basic and diluted share, compared to a $21.1 million net loss, or a loss of $1.46 per basic and diluted share, in the fourth quarter of 2012. The fourth quarter results included CircuLite's operations for the month of December, as well as approximately $6.7 million of non-recurring costs as set forth in this release under "Reconciliation of GAAP to Non-GAAP Net Loss per Share." For the fiscal year ended December 31, 2013, the company recorded a net loss of $59.3 million, or a $3.69 loss per basic and diluted share, compared to an $87.7 million net loss, or a loss of $6.15 per basic and diluted share, in fiscal year 2012.

Non-GAAP net loss per share for the fourth quarter of 2013 was $0.92 per basic and diluted share, compared to a loss of $1.46 per basic and diluted share in the fourth quarter of 2012. Non-GAAP net loss per share for 2013 was $3.24 compared to a loss of $6.07 per basic and diluted share in 2012. See "Use of Non-GAAP Financial Measures" and "Reconciliation of GAAP to Non-GAAP Net Loss per Share."

At December 31, 2013, HeartWare had $201.7 million of cash, cash equivalents and investments.

Use of Non-GAAP Financial Measures

HeartWare management supplements its GAAP financial reporting with certain non-GAAP financial measures for financial and operational decision making. For example, we use "non-GAAP net loss" and "non-GAAP net loss per share" to refer to GAAP loss per share excluding certain adjustments such as amortization of intangible assets, impairment charges, purchase accounting and acquisition related transaction costs, and restructuring and severance costs. These are non-GAAP financial measures under Section 101 of Regulation G under the Securities Exchange Act of 1934, as amended. Management believes that providing this additional information enhances investors' understanding of the financial performance of the Company's operations and increases comparability of its current financial statements to prior periods. Non-GAAP measures should not be considered as a substitute for measures in accordance with financial performance in accordance with GAAP, and they should be reviewed in comparison with their most directly comparable GAAP financial results. Reconciliations of HeartWare's GAAP to non-GAAP financial measures are provided at the end of this release under "Reconciliation of GAAP to Non-GAAP Net Loss per Share."

(a)

Represents amortization of purchased intangible assets related to WorldHeart and CircuLite as well as $3.7 million related to goodwill and in-process research and development impairment charges related to WorldHeart during the quarter ended December 31, 2013.

(b)

Represents acquisition transaction costs associated with the purchase of WorldHeart in August 2012 and CircuLite in December 2013.

(c)

Represents separation costs incurred in connection with the termination of certain employees of CircuLite during the quarter ended December 31, 2013.

We exclude amortization of purchased intangible assets and periodic impairment charges related to long-lived assets from this measure because these charges do not represent what our management believes are the costs of developing, producing, supporting and selling our products and the costs to support our internal operating structure.

2)

We exclude purchase accounting adjustments and acquisition related costs from this measure because they occur as a result of specific events and are not reflective of our internal investments and the ongoing costs to support our operating structure. Purchase accounting adjustments include contingent consideration fair market value adjustments.

3)

We exclude restructuring and severance costs from this measure because they tend to occur as a result of specific events such as acquisitions, divestitures, repositioning our business or other unusual events that could make comparisons of long-range trends difficult and are not reflective of our internal investments and the costs to support our operating structure.

Non-GAAP net loss per share is calculated by subtracting the total per share effect of these adjustments from GAAP EPS.
